[U-Boot] [PATCH] Add support to mkconfig for setting simple #defines in config.h

To simplify the top level makefile it useful to be able to set
some #defines in config.h to express different configurations.

Added a -D option that allows us to replace:

MPC8536DS_36BIT_config \
MPC8536DS_config: unconfig
@mkdir -p $(obj)include
@echo "#define CONFIG_$(@:_config=) 1" >$(obj)include/config.h
@$(MKCONFIG) -a MPC8536DS ppc mpc85xx mpc8536ds freescale

with:

MPC8536DS_36BIT_config \
MPC8536DS_config: unconfig
@$(MKCONFIG) -D $(@:_config=)=1 MPC8536DS ppc mpc85xx mpc8536ds freescale
